31 Days of Mango [Developers]

For the devs out there who are interested in picking up some new tips or tricks, you'll want to check out Jeff Blankenburg's new project "31 Days of Mango" where he'll be ..."publishing a detailed tutorial on Windows Phone development each day this month, specifically focusing on the new additions that were introduced with the Mango update."

Sounds like a great crash course for those both new and experienced, so you'll want to bookmark and check back every day.
